I use a RT3290 Wireless 802.11n 1T/1R PCIe wifi card. This card does not has a proper driver for ubuntu, I tried several post but I had no luck. Now I've tried to install windows driver for the card using Windows Wireless Drivers, and I have attached the picture.

enter image description here

Here the driver installed properly. But after installation the driver is not recognized by the Ubuntu. Here is the output of sudo lshw -C network

rashed@rashed-HP-250-G3-Notebook-PC:~$ sudo lshw -C network[sudo] password for rashed:

Output of iwconfig is 

eth0      no wireless extensions.

lo        no wireless extensions.

And the out put of sudo modprobe ndiswrapper and then dmesg | grep ndis is 

rashed@rashed-HP-250-G3-Notebook-PC:~$ sudo modprobe ndiswrapper
[sudo] password for rashed: 
rashed@rashed-HP-250-G3-Notebook-PC:~$ dmesg | grep ndis

As you can see, for the wireless card, the the error message -network UNCLAIMED is there. Now if any one has a solution for this I would really appreciate to share it with me. Thanks in advance.

Run the following command: 

sudo modprobe ndiswrapper

If this show you "Required key not available",then follow this link. I don't have much knowledge of Ubuntu but this fixed my problem.
